Nginx 1.0.15 and 1.1.19 for Windows (32-bit and 64-bit) were all built from the upstream developers at nginx.org. These packages are now available for free download. Please read on for details.
Nginx 1.0.15 stable and Nginx 1.1.19 development versions have been released. Matthew Daley discovered a security problem in the ngx_http_mp4_module, CVE-2012-2089.
A specially crafted mp4 file might allow to overwrite memory locations in a worker process if the ngx_http_mp4_module is used, potentially resulting in arbitrary code execution. This module is not built by default, and has not ever been in any of my builds.
These executables are provided to support legacy users who still use the Cygwin based builds. Official native Windows builds are available and supported at nginx.org.
If you are just starting out, you are better off using the native Windows builds which are supported and available for download at nginx.org.
